Yes, they are awesome lanterns. Locally we have loads but they're not due for removal for a long time yet. and considering they survived the countless PFI's since the 80's, i doubt they'll be removed any time soon... good . I've been after some with a clear cone, refractor rng, and wide 24" canopy, for SOX lamps, And one or two gear in head REVO Solumbras, for SOX.
